error inserting an array in codeigniter - php

Question

when I insert an array in the db, I get the error "unidentified index" in some of the variables even though they all have their corresponding values. Tried using print_r, and it returned an array with values, but when I try to insert the array, the values become null. I dont understand why and I can't see the error in my code.
here's my controller
public function test()
{
if($this->session->userdata('logged_in'))
{
$session_data = $this->session->userdata('logged_in');
$user_id = $session_data['user_id'];
$table_id = $this->input->post('table');
$start = $this->input->post('start');
$end = $this->input->post('end');
$query = $this->process_resto_list->test($table_id);
if ($query->num_rows() > 0)
{
$row = $query->row();
$resto_id = $row->resto_id;
$table_number= $row->table_number;
$table_size = $row->table_size;
}
//$resto_id = $session_data['user_id'];
$values = array(
'resto_id' => $resto_id,
'diner_id' => $user_id,
'date' => $this->input->post('date'),
'start_time' => $start,
'end_time' => $end,
'table_number' => $table_number,
'number_of_people' => $table_size,
);
if($this->process_resto_list->insert_reservation($values))
redirect('reservation_test/reservation', 'location');
//print_r($values);
}
Here's my model
public function insert_reservation($values)
{
date_default_timezone_set("Asia/Manila");
$data = array(
'resto_id' => $values['resto_id'],
'diner_id' => $values['user_id'],
'date' => date('Y-m-d'),
'start_time' => $values['start'],
'end_time' => $values['end'],
'table_number' => $values['table_number'],
'number_of_people' => $values['table_size'],
);
return $this->db->insert('resto_reservations', $data);
}
When using print_r here's the result of the array
Array ( [resto_id] => 9 [diner_id] => 14 [date] => [start_time] => 11:00 [end_time] => 13:00 [table_number] => 6 [number_of_people] => 4 )
Please help me point out the error. Thank you

Answer 1

In your model. Change values as follows
$data = array(
'resto_id' => $values['resto_id'],
'diner_id' => $values['diner_id'],
'date' => date('Y-m-d'),
'start_time' => $values['start_time'],
'end_time' => $values['end_time'],
'table_number' => $values['table_number'],
'number_of_people' => $values['number_of_people'],
);

I just replaced my model with this. Thanks everyone!
$data = array(
'resto_id' => $values['resto_id'],
'diner_id' => $values['diner_id'],
'date' => date('Y-m-d'),
'start_time' => $values['start_time'],
'end_time' => $values['end_time'],
'table_number' => $values['table_number'],
'number_of_people' => $values['number_of_people'],
);
